A marshmallow is a sugar based candy that, in its modern form, typically consists of sugar, whipped to a spongy consistency, molded into small cylindrical pieces, and coated with corn starch. Some marshmallow recipes call for eggs. This confection is the modern version of a medicinal confection made from Althaea officinalis, the marshmallow plant.
